sharpness is more than just
megapixels
Resolution is the sum of several parts in the imaging
chain, starting from how we capture images, how much
hand-shake is involved, and ending with technical func-
tions including the camera optics, the image sensor, and
the algorithms. It´s not enough to just include a high
megapixel sensor – the lenses conveying the image to
the sensor have to be of equally high quality.

Together with our partner Carl Zeiss, we yet again
pushed the limits of optical design to match the reso-
lution of the 41 megapixel camera sensor. To provide
the best optical resolution we increased the number of
lenses used from the five in the award-winning Nokia
808 PureView, to six. The first lens element is made of
high precision glass, and five of the lenses are mould-
ed high-performance plastic, taking lens manufacturing
precision to the next level.

The lenses are physically very big for a smartphone, and
the optical assembly alone is unique. But that is not all.
We put the whole system inside a completely new kind
of optical image stabilisation system, which uses an
extremely high accuracy sensing system linked to very
small motors which actively move the lens.

The extremely sharp image projected by the six-element
lens system is recorded by the second generation 41MP
BSI sensor, capturing even the smallest of details in the
scene, including detail not visible to the naked eye.

The 41MP sensor can capture 34MP and 38MP image
files at 16:9 and 4:3 aspect ratios respectively. In addi-

tion to the 38MP and 34MP full-resolution images, the
Lumia 1020 camera captures 5MP oversampled images
so that every pixel in the 5MP image has been created
using the data from up to seven pixels of the sensor.
The oversampling technology ensures that these 5MP
images are incredibly sharp, natural and low noise. The
best part is that the camera saves both the full resolu-
tion and oversampled image simultaneously.

This is referred to as dual capture. It enables creative
post-processing while still allowing users to share a
high-quality small file size image straight after shoot-

why 5mP?
5MP is the sweet spot for image quality that is easy to
share and printable up to A3 size. And because our 5MP
images condense the information from the 41MP sen-
sor, they have amazingly high image quality.

The 5MP images get the full benefit of the oversampling
technology and their quality is way above that produced
by any traditional imaging device. In addition to over-
sampling, the 41MP sensor can also be used for lossless
or high resolution zooming (see page 6).
